c# - Asp.net Core 中的 HttpRequestException : An error occurred when retrieving Google user information (Forbidden).

Question

我正在尝试在我的 asp.net 核心应用程序中启用社交登录。我已经成功整合了 facebook 和 twitter，并且运行良好。但是在集成 Google 时，在返回到回调 URL 时它会吐出此错误页面。

我也在为这个过程使用自定义 Controller

[Route("signin/{provider}")]
public IActionResult SignIn(string provider, string returnUrl = null) => 
        Challenge(new AuthenticationProperties { RedirectUri = returnUrl ?? 
          "/" }, provider);

上面的代码是我的自定义 Controller 调用auth.cs。

services.AddAuthentication(options => {
     options.DefaultAuthenticateScheme = 
CookieAuthenticationDefaults.AuthenticationScheme;
     options.DefaultChallengeScheme = 
CookieAuthenticationDefaults.AuthenticationScheme;
     options.DefaultSignInScheme = 
CookieAuthenticationDefaults.AuthenticationScheme;
})
.AddFacebook(options => 
          {
            options.AppId = "";
            options.AppSecret = "";
        })
.AddTwitter(options =>
        {
            options.ConsumerKey = "";
            options.ConsumerSecret = 
"";
})
.AddGoogle(options => {
            options.ClientId = 
"<my client Id>";
            options.ClientSecret = "<my client secret>";
})
.AddCookie(options => {
            options.LoginPath = "/auth/signin";
});

我预计一旦我使用 googles Oauth 2 登录。* 它应该重定向回我的应用程序而不是显示错误页面

试试这个:

.AddGoogle("Google", o=>
{
    o.ClientId = "<insert here>";
    o.ClientSecret = "<insert here>";
    o.UserInformationEndpoint = "https://www.googleapis.com/oauth2/v2/userinfo";
    o.ClaimActions.Clear();
    o.ClaimActions.MapJsonKey(ClaimTypes.NameIdentifier, "id");
    o.ClaimActions.MapJsonKey(ClaimTypes.Name, "name");
    o.ClaimActions.MapJsonKey(ClaimTypes.GivenName, "given_name");
    o.ClaimActions.MapJsonKey(ClaimTypes.Surname, "family_name");
    o.ClaimActions.MapJsonKey("urn:google:profile", "link");
    o.ClaimActions.MapJsonKey(ClaimTypes.Email, "email");
})
